Coconut Raw Sugar Ice Cream
1. In a saucepan, heat the turbinado sugar with one-quarter of the coconut milk, stirring, until smooth and bubbly.
1. Preheat oven to 375°F and butter an 8-inch round baking pan. Line bottom with a round of wax paper and butter paper.
2. Chop chocolate into small pieces. Put in a large Pyrex measuring cup with butter and heat in microwave, stirring every 30 seconds, until melted and smooth.
3. Transfer melted chocolate to large bowl and whisk in sugar. Add eggs and whisk well.
4. Sift 1/2 cup cocoa powder over chocolate mixture and whisk until just combined. Pour batter into pan and bake in middle of oven 25 minutes, or until top has formed a thin crust.
6. Cool cake in pan on a rack 5 minutes and invert onto a serving plate.
Make the chocolate génoise:
1. Preheat the oven to 350°F. Butter a 9-inch round cake pan. Dust the pan with cocoa powder and tap out the excess.
2. Whisk together the flour and cocoa powder in a medium bowl; set aside.
3. Fill a pot one-third full with water and bring to a simmer. Combine the eggs and sugar in the bowl of a standing mixer. Place the bowl over the simmering water and whisk until the mixture is warm to the touch. Transfer the bowl to the mixer stand and, using the whisk attachment, beat on medium speed until the mixture triples in volume and forms a thick ribbon when the whisk is lifted, about 8 minutes. Using a large rubber spatula, gently fold in the flour mixture. Fold in the melted butter. Scrape the batter into the pan and smooth the top.
4. Bake the cake for 20 to 25 minutes, until it has pulled away from the side of the pan and the top springs back when lightly touched. Cool the cake in the pan for 10 minutes. Unmold the cake on a rack and cool completely, right side up.
Make the caramelized white chocolate:
5. Preheat the oven to 250F.
6. Distribute the white chocolate on a rimmed baking sheet and heat for ten minutes.
7. Remove it from the oven and spread it with a clean, dry spatula.
8. Continue to cook for an additional 40-60 minutes, stirring at 10 minute intervals. At some points it may look lumpy and chalky, but keep stirring and it will smooth out and caramelize (or not, as in my case).
9. Cook until the white chocolate is deep-golden brown, and caramelized (or until it tastes caramelized, even if still lumpy).
10. If it's lumpy, scrape it into a bowl and smooth it out with an immersion blender, or in a food processor, and add up to 1/2 cup heavy cream to smooth it out and make it pourable.
Make the white and dark chocolate mousses:
11. In the bowl of an electric mixer, using the whisk attachment, beat 2 1/2 cups of the heavy cream to soft peaks. Scrape half of the whipped cream into a medium bowl. Cover both bowls and refrigerate.
12. Put the white and dark chocolate in two separate medium bowls. Bring the remaining 1 cup cream to a boil in a small saucepan. Pour 1/2 cup of the hot cream over the white chocolate and the remaining 1/2 cup over the bittersweet chocolate. Gently whisk the white chocolate until it is completely melted and the mixture is smooth. Whisk the dark chocolate until smooth.
13. Let the chocolate mixtures cool for 10 minutes. Fold the white chocolate mixture into one bowl of whipped cream. Fold the dark chocolate into the remaining whipped cream.
Make the sugar syrup:
14. Combine 1/4 cup (59 grams) water and the sugar in a small saucepan. Bring to a boil over medium-high heat, stirring to dissolve the sugar. Let the syrup cool to room temperature.
Assemble the cake:
15. Using a serrated knife, slice the cake horizontally in half. Cup a strip of parchment paper to line the inside of a 9x4-inch cake ring. Line the mold with the strip and place it on a serving plate. Place a 9-inch cardboard cake round in the bottom of the cake ring. Place the bottom cake round, cut side up, in the ring. Brush the cake generously with the sugar syrup. Spread 1/2 of the caramelized white chocolate over the cake. Scrape the dark chocolate mousse onto the cake and smooth it into an even layer. Top with the second cake round, cut side down. Brush the cake generously with syrup. Spread the rest of the caramelized white chocolate. Scrape the white chocolate mousse onto it, smoothing it into an even layer. Chill the cake for at least 2 hours and up to 24 hours.
16. To unmold the cake, lift it off the plate, holding it with your palm against the cardboard round. Using a hairdryer or warm damp towel, briefly warm the cake ring mold. Lift off the ring mold and peel off the parchment strip. Allow the cake to stand at room temperature for 30 minutes before serving.
